CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND: │
│ │
│ Use the CPUFreq governor 'ondemand' as default. This allows │
│ you to get a full dynamic frequency capable system by simply │
│ loading your cpufreq low-level hardware driver. │
│ Be aware that not all cpufreq drivers support the ondemand │
│ governor. If unsure have a look at the help section of the │
│ driver. Fallback governor will be the performance governor.
